text: The LP record The Best of the Johnny Mann Singers: Underground at the Fair played in background of the exhibit; it did not sell well. This was its only appearance in pop culture (save in the niche mythos of urban exploration, and as one of the oddities of architecture) until its interior was reproduced in the 2009 CSI: NY episode Manhattanhenge as the anachronistic lair of a mad killer, the structure supposedly simply having had soil layered on top of it and been abandoned. The set was complex and impressive.
